GASKET Filed July 7, 1925 INVENTOR CLYDEQF'ARMER BY ATTORNE rarefied et-.2 9 M Application filed" Jul 7,

i This invention relates to gaskets, andmore particularly'to a gasket adapted to'make a tight joint between two members havinga plurality of connectingopenings for the pasQ sage of fluid under pressure.

l Vith a gasket of the above character, openings are'also provided for boltsemployed in,

i members.

r heretofore beenneoessary to apply the gasket an r i 4 n u openings in the gasket will register with the members, with "the result "that securing the members together, and it has in a position suchthat the fluid pressure ister with the securing bolts and yet ensure that all of the fluid pressure openings will register properly. r y T In the accompanying drawing; Fig. l is a face View of a member having agasketface rovided with openin s a asket a lied .L b 3 b thereto and constructed in accordancewith my invention, and a cover plate clamping the gasket to said member; and Fig. 2 a plan view of a gasket adapted to be applied to the gasket face shown in Fig. 1 and con structed in accordance with my invention.

-Tl1e member .1 shown in Fig, 1 is provided with a gasket 3,062 having a plurality of openings arranged with their centers on a circle. The openings 3 aregbolt openings and are three in number, arranged symmetrically, and openings 4: are provided for the passage of fluid under pressure and may be located unsymm'etrioally, as "shown.

The gasket 5, as shownin Fig. 2, is provided with belt openings 6, arranged sym metrically and adapted to register with the gasket is adaptedto be clamped between the bolt openings 3 in the gasket face 2, and said member 1 and'a cover plate 8 by means of bolts 9. It will be seen that when the gasket is applied to thegasket face and any one of i the bolt openings 6 of the gasket 5 is in registry with one of thebolt openings 3,.the

long as the'gasket is applied with the bolt openings 6 in registry with the bolt openi v i ings 3 in the gasketface.

V It will be notedthat thebolt areof larger diameter than the openings 7 openings 6 so that connecting bolts of the same diameter; r can only enter the bolt openings 6 and'this prevents applying the gasket except withthe bolt openings 6 registering with the-bolt openings 3, and on the other hand, there will always he openings 7 in registry with the open ings] 4, regardless of which bolt opening 6 happens to register with a particular bolt opening 3 in the gasket face. r i

It will now be evident that by construct ing the gasket in accordance withmy inven-,

tion, it is impossible to apply the gasket in i such a manner as to block or cut ofi any of the fluid pressure openings in the gasket face.

Havingnow described my invention, what ters Patent, is: l

1. The combinatlonwith a member having a gasket face provided with openings I claim as new and desire to secure by Lethaving their centers on the same circle, somcf of the openings being symmetrically disposed bolt openings and the other openings being unsymmetrically disposed fluid pres sure openings,'and a-cover plate of a gasket interposed between said member and said plate and having symmetrically disposed bolt openings adapted to register with the will register with the unsymmetrically disposed fluid pressure openings in the gasket face, whenever the boltopenings in the gasket register with the bolt openings in said member. 7 r

2. The combination with a member having a gasket face provided with openings having their centers on the same circle, some of the openings being equally spaced bolt openings and the other openings being unequally spaced fluid pressure openings, and a cover plate of a gasket interposed between said member and said plate and having bolt openings equally spaced to correspond with the bolt openings in the gasket face and equally spaced fluid pressure openings, some of which will register with the unequally 75 spaced fluid pressure openings in the gasket face in any position in which the gasket may be applied with the bolt openings of the gasket in registry with the bolt openings in the gasket face, the bolt openings being of 29 greater diameter than the fluid pressure openings to receive bolts of a corresponding diameter.

In testimony whereof I have hereunto set my hand. 25 CLYDE C. FARMER.
